FORUNWINDING'GAKES AND 1 OTHER rAoKAG s 7 6. llanseplhiladelphia, Paassignor to Am ican ,Viscose Corporation, Wilmington, De ta or or t n ofla are Application October 30, 1946, s r ai'ivog 'zoenoe This inventionrelates to improved fiyers for unwinding cakes, cops, bobbins and otherpackages on which yarn, thread, strands and other filamentary materialsare wound.

In-devices of the prior art, the necessity often arose wherein it wasexpedient to replace the traveler on the fiyer assembly, because ofundue wear or the like; This usually meant that either most ofthe fly'erhad to be disassembled or the fiyer had to be scrapped. Thisdisadvantage of the prior art is overcome in the present invention.

The primary object of this invention is to provide 'an improved fiyerand traveler with means for readily removing the traveler from theflyer.

Other objects and: advantagesyof the present invention will becomeapparentfrom a study of the description ofthe drawings herein.

In the drawings:

" Figure-3 is an end view of the vertical armof the flyer of Figure 1,Figure 4 is a modification using a circular shank traveler, and I Figure5 is a modification using a straight shank traveler. 1

' As shown in Figures 1 and. acter 2 indicates a holder on which a woundcake is supported. This ma be a cake 3 produced in a spinning pot, suchas is used in the rayon industry. The spindle 4 which protrudes throughthe center of the cake has a collar 5 mounted near its free end. Thespindle 4 may be made so that' the cake fits loosely or tightly, howeverit is preferable that it fit tightly in order that it restrict rotationof the cake thereabout. The collar 5 supports a hub 6 rotatably mountedthereon. The hub 6 may be equipped with a plain, self-lubricating oranti-friction bearing, the main consideration being that the device beas free-running as possible.

The hub 6 supports the frame I mounted generally perpendicular to itsaxis of rotation. The frame 1 consists of two laterally displaced rodssuch as wire or the like. Although the frame l is mounted generallyperpendicular in this case, it can be mounted at any angle and stillproduce good results. Adjustably mounted on the free end of the frame 1is a counterweight 8, that. smooths the rotation of the fiyer assembly9. The frame I is constructed in such a way that part cake or otherwound package 3. 'I'hi.s part of the 2, reference charthe axis ofrotation of the fiyer. mounted at the bend in the frame I is a porcelaineye [0, through which passes the yarn l I from the frame maybeconstructed so that His other than parallel to the cake, but it has beenfound that the best results are obtained when it is parallel. The wires,as shown in Figures 1 and 2, are .in a common plane which extendstransve'rsely to a plane containing one of the wires and Suitablycake'3, via the traveler l2 whose vertical travel is limited by stops [3and. I

The frame 1 is constructed so that the traveler |2 can be replaced bysqueezing the two rods,

wiresor the like together, whichaction allows thetraveler to be removed.These rods or wires are resilient so that they will regain theiroriginalthe internal diameters or dimensions of the traveler are different, thelonger dimension adapting the traveler to slidably embrace the rods Iwithout distortion thereof, and the space within the interior of thetraveler as viewed in Figures 4 and 5. (i. e. in a direction at rightangles to the plane of the traveler) .is ovate or elongate. The gap lidis disposed in one of the longer sides of the traveler so that, inoperation, the traveler cannot rotate relative to the parallel rods 1 ofthe frame. In operation, the traveler is mounted on rods 1 with theclosed side of the traveler towards the package 3 and the gap away fromthe package. It is important that any type traveler used must have a gap[2a in it so thatit can be removed from the frame.

As shown in Figure 2, the flyer assembly 9 may be modified so that itcan be used on a cake holder that is in any position from the horizontalto the vertical. The free end of the spindle 4 is threaded toaccommodate the lock nut I6, which bears upon a washer or the like [5holding the spring I! against the washer or the like l8 which creates abearing surface for the flyer hub 6. With an assembly of this sort, itis easy to remove this spring device because it does not have to be inplace when the cake holder 2 is in the horizontal position.

In operation, the thread, strand, yarn or other filamentary material istaken from the cake 3 and passes through the traveler l2 and from therethrough the porcelain eye I0. As the yarn is drawn ofi the cake, thefiyer rotates and the traveler reciprocates between the two stops l3 andM. The frame .1, is of such a resiliency that it will 1.
